Error on DB dump

Hi,

After importing a DB dump, I give this error in drush:

Strict warning: Drupal\Core\Form\FormBase and Drupal\Core\Messenger\MessengerTrait define the same property ($messenger) in the composition of                                         [error]
Drupal\taxonomy_manager\Form\MoveTermsForm. This might be incompatible, to improve maintainability consider using accessor methods in traits instead. Class was composed in include()
(line 105 of modules/contrib/taxonomy_manager/src/Form/MoveTermsForm.php). include('/var/www/drupal-8/modules/contrib/taxonomy_manager/src/Form/MoveTermsForm.php') (Line:
444)

I'm unable to identify me as admin editor.

Thanks
